Sounds like it could either be a spun out main bearing or camshaft bearing or it could be knocking from low octane gas, depending on how loud it is. A main bearing or camshaft bearing that is spun will make an unmistakably loud cyclic noise. While, the low octane gas will cause a softer random rapid knocking sound that sounds like a babbling brook. Check for codes in the engine that might explain why there is an octane related knock, like a knock sensor not working or something like that. Good luck on finding a solution to your knocking problem.

Have a knock on 2002 Chrysler concorde lxi has 3.5 engine. is worse when accelerating.


Dear Dennis,
Mechanics will tell you you have an engine that is about to blow up. This is the symptom of such a question.
I should recommend you not attempt to even start the car at all. Have it towed to a honest garage for a true diagnosis.
The repair may run from many hundreds up to a couple thousand dollars.
God bless your efforts.

2003 chrysler concord nocks pings left side


Knocking and pinging are two separate things. "Knocking" usually refers to the sound an engine makes when internal mechanical parts, such as piston rod bearings or connecting rod bearings, begin to wear and cause a deep "knock, knock, knock" sound during engine rotation. "Pinging" refers to the tapping sound you get upon acceleration, either when using fuel that is to loo octane for the vehicle, or when static timing is set too far advanced, or when the cylinder heads are overheating due to clogged water channels or thin oil.
If you are hearing KNOCKING on the left side, it is likely time for an engine rebuild. If you are hearing PINGING, you may need a better grade of fuel, or you are way overdue for either an oil change or a major tune-up.

Sounds like the timing belts needs to be replaced and it is a real pain on those cars best to do the water pump also. I suggest a really good mechanic do the work though. It took me about 8 labor hours to do this.
